Swap between 2 face index

  • You want to use the .faceIndex value of a head binding component.

    First import both of them,

    //@input Component.Head headOne

    //@input Component.Head headTwo

     

    then setup a variable to know when it's switched.

    var switch =  false

     

    next, setup your tap event. I actually use Touch Start here because it detects taps faster.

    var event = script.createEvent("TouchStartEvent");

    event.bind(function(eventData)

    {

    // put code here

    });

    Then inside that you want to change the switch variable to its opposite and set the face indexes based on that:

    switched = !switched

    if(switched){

    script.headOne.faceIndex = 1

    script.headTwo.faceIndex = 0

    } else{

    script.headOne.faceIndex = 0

    script.headTwo.faceIndex = 1

    }

     

    so the full script would be:

     

    //@input Component.Head headOne

    //@input Component.Head headTwo

    var switched = false

    var event = script.createEvent("TouchStartEvent");

    event.bind(function(eventData)

    {

    switched = !switched

    if(switched){

    script.headOne.faceIndex = 1

    script.headTwo.faceIndex = 0

    } else{

    script.headOne.faceIndex = 0

    script.headTwo.faceIndex = 1

    }

    });

    You may want to consider this to stop the camera from flipping if spamming tap:
